ABSTRACT:
A camera comprising a document table for placing a document thereon, a photographing assembly for photographing the document on the table on a film on a reduced scale, and a marking assembly for photographing on the film a size mark corresponding to the size of the photographed image. When documents of different sizes are photographed on the same reduced scale by the photographing assembly, the corresponding size mark provided by the marking assembly is also photographed on the film in the vicinity of each film image. Such size marks recorded serve as image size data when the film images are thereafter copied by a reader-printer or printer on an enlarged scale, and are useful for automatically selecting copy paper of suitable size.
